Sherlockapp.com is a browser-based AI face search and people-finding service. Users upload a photo of one face, and the service searches social platforms and the public web for visually similar profiles and pages. Results include confidence percentages to help users assess each match; these scores are indicators, not proof of identity. The service lists coverage across Instagram, TikTok, Facebook, X, LinkedIn, YouTube, Pinterest, OnlyFans, and the wider public web.

Sherlockapp.com works on mobile and desktop browsers, including iPhone, Android, and desktop devices, with no app download required. It is designed for uses such as checking whether a dating profile photo may be misleading, verifying an online seller or contact, spotting possible catfishing, and finding where a user’s own photos appear online. The company says uploads are used only to perform searches, results are private to the user, and photos are not added to a public index. It advises users to verify matches at their original sources, since image quality affects results and false positives can occur.
